DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 to 8 thereof, a new and improved barricade light lock apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The FIG. 1 illustrates a prior art barricade structure as set forth in U.S. Pat. No. 3,506,959 utilizing threaded members to secure the illumination housing to the barricade structure. The U.S. Pat. No. 4,516,109 as exemplified in the FIG. 2 illustrating the bracket structure to mount the illumination housing relative to the barricade apparatus.

More specifically, the barricade light lock apparatus 10 of the instant invention essentially comprises a barricade assembly 11 including a first pair of spaced parallel legs 12 cooperative with a pair of second spaced parallel legs 13. A first connector panel 14 is directed orthogonally between the first spaced leg pairs 12, with a second connector panel 15 orthogonally directed between the second spaced parallel leg pairs 13. A first and second leg of the first and second leg pairs respectively is joined together at a first junction 16, with a second junction 17 formed by joinder of a further first and second leg member of the first and second leg pairs 12 and 13, as illustrated in the FIG. 3. The first junction 16 includes a first junction bore 18 orthogonally directed through the first junction, wherein a second leg bore 19 directed through a second leg below the first junction bore 18. A lock member 20 including a lock member loop 21 is directed through the second leg bore 19. An illumination housing 22 is positioned upon the barricade structure, with the illumination housing including a lens assembly 23 mounted thereon. The lens assembly includes an illumination bulb 24 positioned therewithin. The illumination housing 22 includes a housing threaded bore 25 that is coaxially aligned with and adjacent the first junction bore 18. In this manner, an externally threaded lock rod 26 is directed through the first junction bore 18 and threadedly received within the housing threaded bore 25. The externally threaded lock rod 26 includes a lock rod head 27 extending diametrically beyond the lock rod 26 at a rear distal end of the lock rod spaced and positioned in abutment with the first junction 16 on an opposed side relative to the housing 22. The lock rod head 27 includes a handle 28 orthogonally mounted to the lock rod head, with the lock rod handle extending downwardly thereof and directed through the lock member loop 21 preventing rotation of the handle relative to the lock rod 26 and thereby preventing removal of the lock rod and of the associated housing 22.

The FIGS. 7 and 8 illustrate a further aspect of the invention, wherein removal of the lock rod 26 effects an operation of the housing 22 to discourage removal of the housing 22 relative to the barricade structure. The housing 22 includes the illumination bulb formed with illumination bulb first and second electrical line 29 and 30 directed into the housing 22 from the lens assembly 23. The first electrical line 29 is directed into a first electrical tube 31, with the second electrical line directed into a second electrical tube 32. The first and second electrical tubes 31 and 32 are coaxially aligned with the housing threaded bore 25 to effect electrical intercommunication of the first and second electrical lines 29 and 30 to permit transmission and completion relative to the illumination bulb 24 in association with a battery member "B" positioned within the housing 22. Removal of the lock rod 26 effects immediate visual alert as to the removal of the illumination structure.

As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
